Botryoidal Malachite

Description

A substantial, sculptural Malachite specimen with rounded growth, flowing green banding and an acrylic stand made for its display.

This large Malachite from the Tonglushan Mine in Hubei Province is built from rounded botryoidal forms that rise and fold around one another. Its colours range from deep forest green to brighter jade green, with concentric “eye” banding visible in several exposed areas.

The close photographs reveal smooth, gently lustrous surfaces alongside smaller rounded growths and natural openings. The upright shape gives it a strong display presence, and the included custom acrylic stand supports the specimen for viewing from several angles.

It weighs 3.887 kg and measures 330 × 270 × 100 mm.

The rounded, botryoidal growth described here is an aggregate habit: many small crystals contribute to a larger curved surface. It offers a different kind of mineral display to a group of sharply pointed crystals. The adjoining rounded areas, recesses and changes in surface texture help bring out the three-dimensional form.

Malachite is a green copper carbonate mineral that commonly forms in the oxidised zone of copper deposits. It is familiar as polished decorative material, but a collector specimen preserves the natural growth surface instead. Rounded botryoidal forms, fibrous aggregates and occasional distinct crystals show a range of textures within the species.

Botryoidal means grape-like: adjoining rounded areas build a larger curved surface. Where that habit is recorded, the outline of the growth can be as appealing as the green colour. Fibrous surfaces may have a softer sheen than distinct crystal faces. The relationship between these textures and the host material makes natural Malachite quite different to a smoothly polished piece.

The recorded origin is Tonglushan Mine, Daye, Hubei Province, China. Within a collection of Malachite specimens, this locality gives the piece a geographical identity alongside its particular crystal habit and natural setting.

The specimen measures 330 × 270 × 100 mm, with a recorded weight of 3.887 kg. Its scale gives the natural architecture room to be appreciated as a whole, while the finer growth provides detail for closer study.

Support the stable matrix or the supplied mount when moving the specimen, avoiding pressure on projecting growth. A secure indoor display allows its natural form and surface detail to be appreciated while protecting exposed crystal edges.
